In response to Mike, you wouldn't find the source code for the Dropbox daemon in any release, as it is proprietary (but still distributable, hence non-free). However, Dropbox's Nautilus plugin is open source, and licensed under the GPLv3 (Rian, please correct me if I'm wrong). Ivan's original Dropbox package in Debian never included the Nautilus plugin though.
I'm a Dropbox + Debian user (and aspiring packager/contributor), so I would be interested in adopting and maintaining this package if Ivan no longer wants to take care of it. I'm very much new at Debian packaging; I've learned the basics during Google Code-In a month ago, but I would definitely appreciate the help of anybody with more experience, and I would also need a sponsor to upload my package once it's done. I'm willing to put in the time necessary to ensure that debian/copyright is compliant with the Debian Policy, but again, I'll need some guidance to do so.
